Description
-----------
The AHT10 is a Temperature and Humidity sensor
The address of this i2c device may only be 0x38
Usage Notes
-----------
This driver does not probe for AHT10 devices, as there is no reliable
way to determine if an i2c chip is or isn't an AHT10. The device has
to be instantiated explicitly with the address 0x38. See
Documentation/i2c/instantiating-devices.rst for details.
